BED-SPRING.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed January 5, 1907. Serial No. 350,954.

To all whom it may concern:

Be it known that I, PAUL SAPPrNeToN, a citizen of the United States, residing at Oarthage, in the county of Jasper and State of Missouri, have invented a new and useful BedSpring, of which the following is a speciiication.

This invention relates to springs for beds, sofas, couches and other furniture and has for its object to provide improved means for locking the upper and lower convolutions of the springs in engagement with the longitudinal and transverse brace-wires of the supporting frame therebyto prevent accidental displacement of said springs.

A still further object of the invention is to generally improve this classof devices so as to increase their utility, durability and efficiency.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification: Figure 1 is a top plan view of a portion of a bed-spring constructed in accordance with my invention. Fig. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1. Fig. 3 is a perspective view of the lower convolutions of one of the springs showing the manner of locking the same to the adjacent intersecting braces. Fig. 4 isa similar view of the upper convolutions of the spring showing the construction of the connecting arm.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved device consists of spaced supporting frames 5 and 6 formed of wire or other suitable material and preferably rectangular in shape, as shown, the upper suporting frame being connected by a plurality of brace-wires 7 and the lower frame connected by intersecting longitudinal and transverse brace-wires 8 and 9.

Interposed between the upper and lower supporting frames are a plurality of coil springs 10 the lower reduced convolution 11 lower convolution, as shown.

The convolution 11 is formed with one or more depressions or sockets 13 and 14 for the reception of the intersecting brace-wires thereby to lock the lower end of the spring against accidental displacement on the adjacent supporting frame.

One of the upper convolutions 15 of each coil is bent downwardly to form a depending seat or depression 16, the wire forming the coil 15 being thence bent or coiled to form the upper convolution 17. The convolution 17 is bent to form an elongated longitudinally disposed loop 18 one wall 19 of which engages the base of the depression 16 while the opposite wall of the loop is extended later,- ally to form a connecting arm 20 terminating in an eye 21 adapted to be coiled around or otherwise fastened to the upper convolution of the adjacent spring, as best shown in Fig. 1 of the drawing.

The upper longitudinal brace-wires or rods 7 extend through the loops 18 and bear against the closed ends thereof and also be neath the upper convolutions 15 and 17 of the springs thus securely locking the loop in engagement with the depression or seat 16 while at the same time preventing lateral movement of the springs on the upper supporting frame.

The connecting arms 20 of the marginal row of springs are preferably bent or coiled around the upper supporting frame, as indicated at 22 while thelongitudinal and trans verse braces of both the upper and lower frame are preferably secured to said frames in a similar manner, as indicated at 23.

Attention is called to the fact that the loop 18 is disposed at an angle to the horizontal plane of the upper convolution 17 of the adjacent spring whereby when the brace 7 is threaded through said loop one wall of the loop will engage the base of the depression while the opposite wall thereof will bear against the inclined wall of said depression, thus forming a double bearing for the loop.

.While the improved spring is principally designed for use on beds it is obvious that the same may be employed with equally good results in connection with. sofas, couches, seats or wherever a resilient support of this character is found desirable.

Having thus described the invention what is claimed is:

1. A device of the class described including spaced supporting frames, coiled springs interposed between said frames and each having one convolution thereof extended laterally'with'm the coil to form a longitudinally disposed loop terminating in an eye for engagement with the adjacent spring, and brace-wires threaded through the loops and secured to one of the supporting frames.

2. Adevice of the class described including spaced supporting frames, coiled springs 1nterposed between said frames and each having its upper convolution extended laterally within the coil to form a longitudinally disposed loop terminating in an eye for attachment to the upper convolution of an adjacent spring, and brace-wires threaded through said loops and extending beneath some of the convolutions of the adjacent springs for attachment to one of the supporting frames.

3. A device of the class described including spaced supporting frames, coiled springs interposed between said frames and each having one of its upper convolutions formed with a depression and an adjacent convolution formed with a longitudinally disposed loop seated in said depression and terminating in an eye for engagementwith the upper convolution of an adjacent spring, and bracewires threaded through said loops and attached to one of the supporting frames.

4. A device of the class described including spaced supporting frames, coil springs interposed between said frames and each having one of its upper convolutions formed with a depression and an adjacent convolution bent to form a longitudinal loop engaging the base of said depression and provided with a connecting arm terminating in an eye for connection with one of the convolutions of an adjacent spring, and brace wires extending through the loops and engaging one of the supporting frames for locking said loops in said depressions.

5. A device of the class described including spaced supporting frames, coiled springs interposed between the frames, a loop having one of its upper convolutions formed with a depression and an adjacent convolution bent to form a longitudinal loop, the wire forming the loop being extended in a horizontal plane to form a connecting arm terminating in an eye for engagement with one of the convolutions of an adjacent spring, said loops being each disposed at an angle to the horizontal plane of the spring, and braces threaded through the loops and extended beneath the upper convolutions of the coils for engagement with one of the supporting frames.

6. A device of the class described including spaced supporting frames, coiled springs interposed between the frames and each having one of its upper convolutions provided with a depression the walls of which converge toward the base of the depression and an adjacent convolution bent to form a longi tudinally disposed loop disposed at an angle to the horizontal plane of the spring and extended to form a connecting arm terminating in an eye for attachment to the upper convolution of an adjacent spring, the walls of said loop being supported in engagement with the base of the depression and one inclined wall thereof, and a brace extending through the loop and engaging the closed end thereof and the bottom of the adjacent convolutions of the spring for engagement with one of the supporting frames.

site directions, intersecting braces connecting the lower supporting frame and seated in said depressions, one of the upper convolutions of each spring being provided with a depression constituting a seat and an adjacent upper convolution bent to form a longitudina lly disposed loop one end of which is extended to form a connecting arm terminating in an eye for attachment to one of the convolutions of an adjacent spring, and braces extended through the loops and beneath some of the upper convolutions of the adjacent spring for attachment to the upper supporting frame for locking the loops in engagement with said depressions.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
